M4.6 Earthquake near Mid-Indian Ridge — March 23, 2025
2025-03-23 22:52:22 UTC (2025-03-23) · approx. 3:52 AM UTC+5 local
On March 23, 2025 at 22:52 UTC, a magnitude 4.6 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -27.5205°, 73.1930°. This earthquake was detected by 25 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
